The DT-TBS is dual-sector, software-defined radio base station system built for the special needs of applications like Search and Rescue (S&R), Portable Network in a Box (NiB), Cellular Identification, Managed Access, and so on.

The platform integrates two digital signal processors (DSPs) and two radio frequency (RF) transceivers. The RF transceivers support any frequency band between 400MHz and 6GHz. The platform has control interfaces to support two external RF front ends (power amplifiers, etc.)

The DT-TBS has a metal casing and can be ordered with or without a fan to accommodate different ambient temperature ranges. It also includes an onboard Environment Management IC (EMIC), which monitors and responds to changes in board temperature and input voltage, and handles other low level hardware management.

An optional “Keep Alive” battery can keep the device fully operational for approximately 5 to 10 minutes to allow “hot swap” of the external power supply.

The embedded Wi-Fi / Bluetooth module enables wireless connectivity to the platform, for example, for controlling from smartphones. It also includes a high sensitivity, 72-channel tracking GPS module for precise location tracking and clock synchronization. Internal Wi-Fi / Bluetooth and GPS antennas are also included. Wi-Fi monitoring requires a separately-orderable Wi-Fi module.

The DT-TBS can be ordered with an optional 3G/LTE UE module or an additional Wi-Fi module. The

3G/LTE UE module can serve as a backhaul interface for NiB applications, for controlling the device remotely. An additional Wi-Fi module includes support for Wi-Fi monitoring.

The DT-TBS includes an SD card interface that can be used for scenario configuration, operation logging, and so on). UART, Ethernet, and user I2C interfaces are available via a digital expansion port.

Each radio can be configured independently to operate as a GSM, UMTS, CDMA2000, or LTE base station.

Additionally, software support exists for cellular scanning (on all 3GPP standards), clock synchronization based on neighboring base stations, and many other features.

The host processor in the DT-TBS is the Freescale i.MX6. The DT-TBS ships with the Linux operating system, including all necessary Board Support Packages (BSPs) for various digital interfaces.

The platform also comes with On Board Management (OBM) software to provide management functions for DSP software booting, interfacing with EMIC, support for external RF front ends, and other hardware access

IMSI/IMEI catching – in this mode the system detects identities of all mobile phones within it’s effective range.

Selective jamming of communication – in this mode system operator can block communication of all mobile phones defined as targets.

Presence verification ‐ This operational mode is intended to detect and select targets of interest (according to IMSI/IMEI identifications) from the total number of subscribers located within operational area of the system.

Data Analysis / Target Correlation ‐ This mode allows the system to detect identities of mobile phones (IMSI/IMEI) which belong to particular targets.

Direction Finding Support – the system forces target’s phone to get into transmit mode (without any visible mark) so that DF / Homing systems can track the transmission direction to identify the target mobile.

Downgrade from 3G / 4G to GSM for operation by an active or passive interception complex
Based on the above capabilities, the system can support variety of operational needs such as:

System can operate with variety of power sources such as AC supply, batteries, car supply etc and by that, it can be installed and operated in many types of applications and environments (fixed installation, remote control configuration, transportable, vehicular, man pack).
